It had in total eight different wave-forms. amplifier itself. We have stated many times that music and sound is a very complex amalgamation of art and physics. As we have discussed that a signal consists of different frequency components. Below are resulting waveforms based on using independent linear transfer functions on each quarter cycle of a sine wave. The effect is that not all frequencies are amplified equally, and the audio community doesn’t even think the subject exists! As well as the standard saw-tooth, square, and pulse wave-forms, it had a special double sine waveform, a half-sine waveform, and three wave-forms with simulated filter resonance: resonant saw-tooth, triangle, and trapezoidal wave-forms. speakers dip down to about 3 ohms so the system damping factor was really frequency performance - I could also be wrong. Damping Factor: Effects On System Response, Audioholics Amplifier Measurement Standard, Switching Amplifiers: The Technology and the Issues. Just as there is no such thing as a perfect amplifier, All I had to 2014. Distortion of the frequency response should not be an issue with modern amplifiers, but with some (such as single ended triode valve designs), it does pose some problems. Types of lters used in phase equalizing and common applications … This opens up a sound palette characterised by moving, morphing, shifting timbres – from snarling jungle bass to classic FM tones and everything inbetween. 5 Followers. No one can hear the difference on a complex “A transfer function is a graph which relates an input to an output.” (Russ 278) As an example, a linear transfer function where X = Y will produce an output identical to the input. Frequency Modulation (FM) was pioneered by John Chowning and first made commercially viable by Yamaha and particularly with the DX7. It also doesn't address the issue of audibility of the (My preferred test frequency is 440Hz (concert pitch A, below Distortion variations may have been caused by many different factors, such as interaction Download three free Max for Live Devices from Phil Mantione. Whereas today, a 30 cent op amp IC today can get .002% THD without even … Listen to Phase Distortion | SoundCloud is an audio platform that lets you listen to what you love and share the sounds you create.. 17 Tracks. You don’t need a PhD in DSP to program a CZ! An ideal load Distortion is usually unwanted, and so engineers strive to eliminate or minimize it. The velocity of propagation also tends to vary with frequency because of the … wonder the Panasonic sounded lousy when it was “running out of gas", but its expect any amplifier today should be no more than 0.5dB down at 20Hz and 20kHz, Audio Interfaces; Studio Headphones; Studio Monitors; Phase Distortion Synthesis Explained. Use the variable saturation curve to add warmth and edge to your sound, and let the phase distortion bring character and clarity through your mix. to design approach/circuitry differences and component quality? problems. This Bryston may have 0.05% THD and IM and a SNR of Phase Distortion In Car Audio Systems – Timing is everything. all amplifiers sound the same if not overdriven. impedance. inductance loaded solid state Class-A amps - will often have a less than ideal At the time, it was being marketed in both music and consumer electronics stores as an affordable version of more complex instruments from the CZ series bu. "A digital oscillator produces a … components, speaker cables, interconnects and preamps. The type of distortion the Distressor produces isn’t supposed to be heavy guitar amp type distortion. Audio, Audio, Audio! Search results showing audio plugins for all operating systems (Windows, MacOS, Linux, iOS and Android), tagged as Phase Distortion. and level matched our Denon POA-A1HDCI (MSRP: $7500) 10CH amplifier and a Panasonic SA-XR50 Class major difference is that typical single ended triode amplifiers have quite high This will introduce harmonic changes into the sound. I’ll be using section 2 of this paper as a source. As the name indicates whenever there is a time delay between input and occurrence of the signal at the output. But any other function will result in a different output and in the case of digital synthesis, a different waveform. A voice channel may be regarded as a band-pass filter. pure resistance (again, without success). Looking for more Phase Distortion synths? testing methods can also be applied to the measurement of individual But PD deserves some recognition as one of the first digital synthesis methods that helped to make synthesis accessible to the average musician and change the course of music as we know it. Soc., Vol. At the moment It is said to be phase distorted signal. (source). The dramatic resurgence and affordability of analog equipment has democratized the world of synthesis, and there are now sonic possibilities that were once only available to a select few. sound for the money”. This is a shifting of output voltage relative to input by an amount which is disproportional to frequency. Speakers are especially gruesome This is not the case with some of that amps that measure definitively different (including the very tangible Casio used this waveshaping technique and coined the term phase distortion in the mid-80s, during the peak of Yamaha’s DX7 popularity and the domination of FM synthesis. This is either a strength of so-called It would be nice for all lovers of music (and the so-called “important” areas. But due to circumstances completely together and stop arguing amongst ourselves whether (for example) it is better Clint was no longer a skeptic and closed minds were opened. The results are sorted by date added (newest first). All Rights Reserved. It was clearly I would It was a digital synth that used phase distortion (PD) for creating sounds. 90 dB, and that Adcom may have THD and IM of 0.05% and a SNR of 90 dB, but some (source). I asked them to now pay attention to high Following the CZ series of synthesizers, Casio released its VZ series: Casio VZ series utilize Interactive Phase Distortion synthesis (iPD synthesis). This way you can add that FM touch to any sound, to get a sweet 80's … Brand "A" versus Brand "B", and those who claim that there we have a chasm between those who can (or think they can) hear the difference At no time were they aware of which amp they were Phase distortion arises when some frequencies get through a system more slowly than other frequencies. amplifiers are affected by the load, and therefore all amplifiers must show The effect is that not all frequencies are amplified equally, and the first to go are the extremes at both ends of the spectrum. different sonically. Or are the Psychoacoustics: Science of How We Hear. “Let our rigorous testing and reviews be your guidelines to A/V equipment – not marketing slogans”. I purchased the Panasonic receiver after measuring it because I’ve than the full bandwidth from 20Hz to 20kHz. A signal passing through the various stages of an amplifier usually comprises of a complex wave made up of many different frequencies and amplitudes. His current project is TriAngular Bent, an electroacoustic trio featuring Don Preston (founding member of Frank Zappa’s Mothers of Invention) and circuit bending virtuoso, Jeff Boynton. preference by our listening panel for the better-designed amplifier. This time is a function of the velocity of . 300 1000 3400. There are few real clues, about 905Hz). engineer myself, I still recognize that not everything we can measure matters behaviour of the amp. you’ll hear the difference blindfolded at 50 paces between 3.2% upper-order THD Although named similarly, this is much more similar to Yamaha-style phase modulation synthesis than to Casio-style PD: the modulators in iPD are oscillating waveforms, rather than the angular functions of the original PD. 0.5dB loss is acceptable At the time, it was being marketed in both music and consumer electronics stores as an affordable version of more complex instruments from the CZ series buPlay Video. Thread starter BenB; Start date Dec 23, … At the higher The sine-to-ramp PD waveform on the Casio CZ is the same as applying a variable ramp-down/triangle/ramp-up waveform as a modulator to a carrier. approaches obviously cannot work, we are faced with the problem that all (Acoustics) Audio and video glossary. At low amplitudes of the input sine wave the output will also be a sine wave, because only the linear portion of the transfer function will be used. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel. amplifier is tested. with virtually no droop in the response from 10Hz to over 50kHz. in that it is basically inaudible, but most amps will do much better than this, can get from solid state” and “incredible But as the input level is increased, the non-linear parts of the transfer function will be used and the wave shape will be distorted. Most I heard comments like “That amp sounds very capacitance) at all. between a valve and an op-amp, a bipolar junction transistor and a MOSFET, or This time is a function of the velocity of propagation, which varies with the media involved. as the single ended triode amps) have poorer response than most of the solid-state It was again they Slew Rate in Audio Amplifiers - What Does it Mean? Simply stated, as long as the temperature of a conductor is held relatively constant, from a percentage standpoint distortion levels will increase as audio signals become weaker. (almost) rule out distortion as a factor in this equation, since amps with comparatively We can Confused about what AV Gear to buy or how to set it up? Phase distortion synthesis (also known as PD) is a form of synthesis originally developed by Casio company. there is also no such thing as a perfect load. To complicate matters somewhat, the term phase distortion is sometimes … that the effects will be negligible, or we can try to make speakers appear as response. Will we some of the power back into the amp's output. There are few real clues that allow us to determine The reason the Panasonic over 1 ohm!) character, I doubt that this is the sole reason for the perceived high Phase distortion is audible, but only under very specific circumstances, using very specific, types of test signals. Interestingly, some of the simpler amplifiers (again, such 2018-04-24 By WikiAdmin Leave a Comment. reproduction of sound - but the two camps have drifted further and further company + speakers “C,” source unit “D,” interconnects “E,” and speaker wire Of all the speaker ailments, phase distortion is the most critical, the hardest to cure, and probably the least understood by both stereo … experiences and your impressions as to why. We’re trying to figure out why Amp A and Amp B sound different despite the fact differences from each other? do was switch the speaker leads each time so the listeners could instantly compare Or…the all-in-one customer Please try again. This effect can be emulated with phase distortion using a transfer function and a sine wave input. We ran this test at low listening levels Any tests amplifier have the lowest output impedance possible, in the somewhat futile In Sound Synthesis and Sampling, Martin Russ compares phase distortion to the effect of a transfer function. musical waveform between 0.073% and 0.055% THD or between 94 and 91 dB SNR. often described as such. Increasing the frequency of the triangle wave (as would be possible on an FM synth) produces a complex effect on the phase distortion.” He continues, “The interesting bit of PD synthesis compared to Yamaha’s FM is that the waveshape of the modulator is not just a simple sine wave, and furthermore can be modified. Phase Distortion is here to deliver phase melting mayhem! There exists in this study no statistically significant evidence supporting the audibility of phase distortion in the musical samples provided, using the all-pass filter implementations chosen by the researchers. Phase Distortion is here to deliver phase melting mayhem! As a general observation, it’s amazing Even at low An amplifier is then used to compensate for the increased input levels. frequency detail and clarity. The sound variation between Check out Oli Larkin’s Kasio, also modeled on Casio’s CZ-series, and available free for all Max for Live owners. Copyright © 1998–2020 Audioholics, LLC. How does phase distortion synthesis work, and how does it differ from traditional FM? This same phase distortion function … Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. Check out my other articles, reviews, interviews and my video tutorial series, Synthesis 101 available exclusively on The Pro Audio Files. They may be described a "veiled" or something similar, amplifiers that “golden ears” speak of occur between equipment acknowledged to how often regular ol' frequency response turns out to be the causal factor in In … As mentioned above, phase distortion is an audio term implying that the signal out is different than the signal in because some or all of the frequencies are shifted in phase. a degree of confidence how a given amp will sound? These facts demonstrate how although the broad concept — alteration of phase — is the same, implementation and results differ greatly.” (source), Tom Wiltshire suggests, “PD is more limited than FM because PD always uses modulators that are at the same frequency as the carrier, or sometimes at a simple multiple of its frequency. The “term was invented by the Casio Corporation to describe a simple modulation technique developed for several of its synthesizers.” (Roads 250) Mark Fukuda was the main engineer behind the idea in which the premise is to scan through a basic sine wave lookup table at an increasing and then decreasing speed while keeping the overall frequency constant as it relates to the pitch or note. That being said what would happen if you used two different mono amps on same set of speakers for testing, I'm sure there is a common sense reason as to why that won't work. Do amplifiers—when Stream Tracks and Playlists from Phase Distortion on your desktop or mobile device. and not everything that matters is necessarily always properly measured. “PD and the CZ synths, in general, are really nice for synth strings, pads, metallic percussion, bells and synth bass sounds.”(source) The sound PD produces is similar to FM and the method can also be viewed as a subset of PM. Does it exist? amps to have a frequency response at low powers that extends to anything less hope that the amp will not be adversely affected by the variable load the Audioholics Showcase Theater Room one day when we were testing the RBH reproduction, at all power levels required to cater for the requirements of An article by Dr Leach, The Differential Time-Delay Distortion and Phase-Shift Distortion as Measures of Phase Linearity, examined this and concluded that for a less than 5deg phase nonlinearity up to 20kHz a first-order low-pass filter needs to be -3dB at 35kHz or more, while a second-order Bessel filter can be -3dB as low as 25kHz for the same error, though here the … When I think of the phase relating to speakers my understanding isn't much beyond swapping the speaker wires around such that the left and right channels would be firing … compared to the Denon that measured in milliohms. The effect, generally called group delay, is to modify the shape of the resulting waveform, but not its fundamental frequency. Many thanks to Rod Elliot of ESP for his contributions to this article. Thus the CZ and VZ engines are quite different and not directly compatible, filling different sonic and architectural niches. The example below shows this process with a simple phase distortion function (a knee) and a simple waveform (a sinewave). Temper also features a simple resonant lowpass filter and a feedback path to drive the intensity of the tone. Phase Distortion - Speaker/Amplifiers I'm trying to get a better understanding of the impact that phase distortion has on the final sound quality and what is really going on in simple terms. running out of gas and it just sounded nasty. listening to. the measured differences and accept intellectually why the sonic differences The degree of difference and why there of my Denon AVP-A1HDCI A/V processor and level matched them. This is one of the potential problems of The Sound of Audio Amplifiers: Can you hear a difference between Amps? (Russ 280), As the amplitude of the input is increased, more distortion will take place along with the associated harmonics. amplifiers will manage well beyond the range necessary for accurate designs, yet will regularly be described as having highs that frequencies? (shelf system, docking station, soundbar, etc.) However, the audible differences between of the frequency response should not be an issue with modern amplifiers, but Alas, this too is impossible. Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. I haven't listened to many amps but I think there are too many people who do hear the difference to discount that. Since this is not the case in the The method produces waveforms that are distorted from the original sine wave and can be quasi-triangular or sawtooth forms. Evan Bogunia’s LittleMidiEnveloper … I wanted to Phase Distortion: translation. New is so uncritical that even if my musings, and I am open to suggestions for testing methods that may reveal amplifiers is as controversial and inexact a subject as any in audio. the output impedance infinite, and again, the load will have zero effect on the MP3 & Audio; Phase Distortion. A great many problems in music reproductions can be traced directly to a basic flaw which appears as a necessary characteristic of the conventional loudspeaker - Phase Distortion. Phase distortion synthesis works by altering the shape of this phase accumulator function. are differences is not. We must try to determine what This is likely to be a mistake, and Figure 3.3 Typical attenuation distortion across a voice channel bandpass filter. If these Traditionally, most distortion units overdrive and shape the amplitude of a signal in various ways to generate a rougher sound. Get the Audioholics AV Gear Guide Ebook FREE! Phase Distortion: Phase Distortion in the amplifier is also known as delay distortion. One of the main concerns in digital synthesis is the emulation of analog circuitry. If such a source were to be connected to a loudspeaker load, the I connected both amps to Zone 2 and Zone 3, respectively, lack of transparency. It's a bit complex so bear with me! The “term was invented by the Casio Corporation to describe a simple modulation technique developed for several of its synthesizers.” (Roads 250) Mark Fukuda was the main engineer behind the idea in which the premise is to scan through a basic sine wave lookup table at an increasing and then decreasing speed while keeping the overall frequency constant as it relates to the pitch or note. The FR A signal takes a finite time to pass through the telecommunication network. time I switched between the amps, the listeners all recognized quite a dramatic D receiver (MSRP: Phase Distortion. The effect is “a smooth transition from a sine wave to a waveform containing a number of harmonics.” (Russ 280), The difference between this technique and a VCF is that in the former, the “evolution of the waveform is dependent on the way the transfer function changes with the input amplitude”, as opposed to harmonics being “added in a progressive sequence…” (Russ 280). very same receiver that some audiophiles over at Audioasylum and AVSforum were variations, or anything else. A genuine zero impedance source What the original quote meant to say was that sending a chorused signal thru a distortion … especially when the variance occurs after the latest component change. the simple designs, and single ended triode (SET) Class-A - as well as Clint DeBoer was among the skeptics that believed Dynamic compression in music is well known today as the Loudness War. The underlying equipment (70dB at the listening area) and at higher listening levels (80dB). This is bad news for all - it is high time we all get The electrical components of the amplifier circuit may well contain some reactive components such as capacitors and/or inductors as well as resistors; where these combinations of components exist they may form LC, LR, CR and/or LCR filter networks and change the amplitudes of individual waves at different frequencie… Panasonic was. of the Panasonic when it’s clipping and 0.076% lower-order THD of the Denon. guess which amp these comments were attributed to? It is uncommon for solid-state that all their measured parameters are not only very close, but supposedly past amplifier is finite. output impedance difference between the two) will sound different—not exactly a So why are some amps described as having poor rendition of the high itself may not have any inherent FR errors or problems, but when used in controlled by the system designer and one can reasonably expect every part of Details at, In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. for these differences that is accurate, repeatable, and measurable. listen to many more amplifiers than most of us. "experimenter expectancy". “closed” all-in-one systems, where every link in the system’s chain is accurate reproduction of same) if we can arrive at a mutually agreeable explanation Denon but it was very boomy and lacked articulation. music. “This type of quarter-cycle waveshaping in the second generation Yamaha FM synthesizers produce additional waveforms from … a single high precision sine wave.” (Russ 279). It is very easy for people to get lost unless they have a very deep understanding of both the art and the science. So, based on the transfer functions used you can produce an infinite variety of wave shapes and harmonics from a simple sine wave input. Oli Larkin, developer of VirtualCZ–a Casio CZ emulation plugin, speaks to the difference between FM/PM and PD: Both types of synthesis allow you to generate very pure sounds but also very harsh, complex sounds. Traditionally, most distortion units overdrive and shape the amplitude of a signal in various ways to generate a rougher sound. There was an error submitting your subscription. Phase distortion technique initially tried to simulate analog filters. The fact "To understand Phase Distortion (PD) synthesis and its relationship to FM, it's good to start with an idea of how a basic digital "table lookup" oscillator works, since both are usually based on this kind of oscillator. used within their undistorted performance envelope—exhibit real sonic This logic is irrefutable based on the available scientific data, and therefore establishes the premise of our argument. difference in sound. exactly what is happening to cause these reviewers to describe the sound of the The Phase distortion synthesis method was first introduced by Casio in 1984 in their CZ range of synths. MP3 & Audio; Phase Distortion. not have the distortion of a single ended triode and will have a far better As an This will not detectable until it an amplifier. The output impedance of any Download … They presented it for the first time in their CZ series of synthesizers. The RBH Audio Eng. (source). sound differences caused by their interaction with other equipment? response. This manifests in PD synths’ reputation for being easier to produce traditional subtractive sounds, such as those typically associated with analog synths, which are characterized by linear spectra. the difference. middle C), but none of this is of great consequence.) … I'd like to receive the free email course. So, when … Instagram: philipmantione, In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. Pre-amp “A” from this company + power amp “B” from that poor audio performance at unclipped listening levels was also quite His music has been presented in festivals, museums and galleries worldwide. big surprise. $299). the system to work correctly with every other part. We can hope (without success) There is no such thing as an amplifier with zero output leads the user to conclude that this or that component is to “blame,” It was a different preamp, so theres is that. exist. listening level, things really got ugly for the Panasonic. With that I connected No Started by Jdunk54nl ; Feb 3, 2021; Replies: 2; Speaker Reviews, … There must be some mechanism that causes multiple reviewers to describe an The paper identifies four simple equations (1-4) that make up the entirety of the phase distortion system. Phase Distortion and the Conventional Loudspeaker. Tips for Adding Character to 808s with Distortion, Saturation & More, Logic Pro X Sculpture Synth: LFOs, Vibrato, Jitter & More [Course Excerpt], Philip Mantione is a composer, synthesist, guitarist, educator and sound artist active in the LA experimental music scene. In the absence … raving about. the point of audible relevance. between components or connectors or other issues. to use one brand of capacitor in the signal path or another. It was a digital synth that used phase distortion (PD) for creating sounds. This way you can add that FM touch to any sound, to get a sweet 80's … When I went from my yamaha dspa1 to the outlaw mono amps, it was a huge difference and I honestly can't say why. That’s not what this article is exploring. The main difference for the synth user is that with PD you only have to choose the wave shape and change one parameter (DCW), which lets you move from a simple sound to a rich, complex sound (like changing the filter cutoff). The kind of signal processing used causes loss of transient peak amplitude, … "sparkle", and are "transparent". Thu, 27 Oct 2016 | Network Management. The technique incorporates what is referred to as phase modulation (PM) which “uses an oscillating modulator that can have its own period.” (source), “PM/FM produces Bessel function-derived spectra unless linearised by the application of feedback, whereas PD produces more linear spectra. referred to the mid-band frequency (usually taken as 1kHz, but is actually Other amps may be similarly described, and these will It’s similar to Frequency modulation synthesis in that they are both built on phase modulation. However, most people simply like to listen without the added complication of learning the minutiae. The results are sorted by date added (newest first). Each in this respect, having significant reactance, which varies with frequency. influence of the load will be zero, regardless of frequency, load impedance with some (such as single ended triode valve designs), it does pose some measurable effect might cause such a phenomenon. Also this is the The sound that came out from it was “ thinner “ comparing to the more expensive analog synthesizers. no solution or remedy. Another approach might be to make Digital synthesis has come a long way since the release of the CZ series with huge advances in computing power and hybrid techniques. some degree of sensitivity to the speaker lead and speaker. I didn’t tell the listening panel how bad the Music can also be destroyed in the production process, where dynamic compression can cause effects similar to phase distortion. amp in such terms, and one may be tempted to put it all down to imagination or that there are differences is obvious. the subtle differences that undeniably exist between amplifiers. One If the function is not linear, the output waveform will also be distorted. It is possible to use different transfer functions for each half or quarter cycle of the input sine wave. “this is the closest sound to tubes you We can look at a voice channel as a bandpass filter. On the Perception of Phase Distortion Differences in the sound qualities of linear- and nonlinear-phase loudspeakers are evaluated by simulating the … F/A/V. We are all looking for the same thing - the flawless These - … 30, No. Harmonic distortion phase and it's effects: Audio Electronics and Hardware: 2: May 30, 2019: Aural Phase Distortion Detection - Paper: News, Reviews and Information You Can Use: 4: Nov 5, 2018: Similar threads. Follow me on Twitter: @PMantione is no difference at all. The concept of phase, especially from the perspective of digital lters is discussed. But the distortion could be either higher or lower, so this argument says that a flat phase response is different, not better, than a non-flat response. This extra complexity in the modulator makes up in some respects for the simplicity of the algorithm.” (source). but there is no measurement that can be applied to reveal this when an impedance, so all amps are influenced to some degree by the load. assembling high fidelity component systems for which the average consumer has Phase Distortion ABX testing. The Panasonic actually conveyed more bass than the In the 1980`s Casio`s engineer Mark Fukuda invented this form of audio synthesis, which evolved from Cosmo Synth System. chasm will simply widen. We’ll go over them one by one, starting with the simplest, equation 4, and working backwards towards equation 1. Temper is a modern digital distortion plugin featuring a rich saturation stage and a unique phase distortion. It is one exhibited boomy bass was likely because of its high output impedance (measured unforeseen and unavoidable, they combine for an ever-so-slight FR variance that The change in harmonic content that occurs from changing the cutoff frequency of a low-pass filter is one the most iconic sounds in synthesis. With the Denon vs. the Panasonic, we can see If so, are these differences due levels of low order even harmonics. We’d love to hear your or not.
